This application is a division of application Ser. No. 10/884,944, filed Jul. 7, 2004, the entire contents of which are hereby incorporated by reference in this application.
The present invention relates to a frame assembly, such as a window frame assembly, including clip(s) for temporarily securing the frames of the assembly for storage and transport and for locking the frames of the assembly upon installation.
Fixed frame window assemblies such as so-called door lights are typically manufactured at a manufacturing facility and then shipped for ultimate installation at another location. Referring to
It is desirable to secure the frame halves to capture the glass panel therebetween during transportation to protect the glass panel from damage, and to ensure that the delivered unit is complete. At the time of installation, screws 20 are threaded through aligned bosses 22, 24 of the frame halves to mount the frame assembly to the door with the glass panel captured therebetween.
Although the frame halves can be secured for transport using the mounting screws 20, such a process would be labor intensive, requiring additional man hours to secure the frame halves with screws for transport and to detach the frame halves for assembly to the door or other structure. Also, the conventional screw boss assembly of the type illustrated in
The present invention provides an attachment structure in the form of one or more clips to temporarily secure the frame halves during transport and to effectively permanently secure the halves during final installation. By providing a clip for final installation, additional fasteners such as screws may be omitted, thereby simplifying and expediting the final assembly process.
Thus, the invention may be embodied in a frame assembly comprising: a pair of frame halves, each including an inner frame portion, an outer frame portion, and an axially extending attachment rib aligned with the attachment rib of the other frame half and terminating in a free edge remote from said inner and outer frame portions; a plurality of spaced locking ribs, each said locking rib extending along a portion of the attachment rib of one of said frame halves, substantially in parallel to said free edge of said attachment rib and remote from said inner and outer frame portions thereof; and a clip structure projecting axially from the attachment rib of the other of said frame halves and engaging one of said locking ribs of the one of said frame halves to secure said frame halves together.
The invention may also be embodied in a method for securing a frame assembly, comprising: providing a frame assembly comprising a pair of frame halves, each including an inner frame portion, an outer frame portion, and an axially extending attachment rib aligned with the attachment rib of the other frame half and each terminating in a free edge remote from said inner and outer frame portions; a plurality of spaced locking ribs, each said locking rib extending along a portion of the attachment rib of one of said frame halves, substantially in parallel to said free edge of said attachment rib and remote from said inner and outer frame portions thereof; providing a clip structure to project axially from the attachment rib of the other of said frame halves; and engaging said clip structure with the attachment rib of the one of said frame halves to secure said frame halves together.
These and other objects and advantages of this invention, will be more completely understood and appreciated by careful study of the following more detailed description of the presently preferred exemplary embodiments of the invention taken in conjunction with the accompanying drawings, in which:
As mentioned above with reference to
Thus, referring to
Conventional screw bosses 122, 124 may be provided to extend in the axial direction of the attachment ribs 130, 140 in a conventional manner and thus are illustrated in
As mentioned above, to secure the frame halves with respect to each other, clip structure 146 is provided to project from one of the frame halves 114 and includes a receptacle 150 for engaging the attachment rib 140 of the opposing frame half 116. In the illustrated embodiment, the clip structure is a separately formed component that is lockingly engaged with the locking rib 134 of one frame half 114 to project axially therefrom. In the illustrated embodiment, the locking clip is axially symmetrical with respect to its centerline. Thus, the locking clip includes first and second receptacles 148, 150 that are generally U-shaped in cross-section for respectively receiving the attachment ribs of the respective frame halves. Locking tabs 152, 154 are provided for lockingly engaging a locking rib of the respective attachment rib. In an exemplary embodiment, the free ends of the legs 156, 158, 160, 162 of the “U-shaped” receptacles 148, 150 are respectively flared to facilitate alignment and mounting to the respective attachment rib, particularly during final assembly through the hole in the door slab or the like.
In the illustrated embodiment, the locking clip is formed by stamping a metal plate, so that one of the legs 156, 160 of each U-shaped receptacle is effectively a frame of material surrounding an opening 159,161 from which the other leg 158, 162 has been stamped and then laterally offset by base segment 164, 166, as shown and understood from
In the illustrated embodiment the clip is provided as a separate component that receives and engages the attachment rib of each frame half in a respective receptacle. However, as an alternative, a clip structure may be provided to integrally project from the attachment rib of one of the frame halves to define a receptacle for receiving the other of the frame halves. It is also to be appreciated that although the clip structure is illustrated as defining a locking tab for engaging a locking rib on an attachment rib of the frame half, the so-called locking rib may be configured as a cavity having a surface for the tab of the clip to engage. Accordingly, locking rib as used herein may be construed as a protrusion on the attachment rib or a recess or cavity on the attachment rib. Similarly, the so-called locking tab(s) of the clip structure may be defined as a protrusion or a recess or cavity, provided that the locking rib and locking tab are configured in a complementary manner so that the locking tab of the clip can slide to or past the locking rib and the locking tab and locking rib can engage to lock the clip structure to the attachment rib.
At the time of final installation, when it is desired to effectively permanently attach the frame halves, the detachably secured frame half 116 is axially shifted to disengage from the clip 146 and is rotated, e.g., by 180 degrees to the position shown in
As can be seen and as will be understood, with the structure of the invention, respective halves 114, 116 of a fixed frame assembly 110 may be temporarily secured for storage and transport (
In an exemplary embodiment, each locking rib has a dimension in the axial direction of the frame assembly of about 2 mm and is disposed so that the locking surface thereof is approximately 6.5 mm from the free edge of the attachment rib. Moreover, in an exemplary embodiment, the locking rib has a transverse height of approximately 1 mm. Finally, in an exemplary embodiment, each discrete locking rib has a length in a direction transverse to the axial direction of the frame of about 35 mm. It is to be appreciated that the dimensions given are by way of example only and are not to be considered limiting with respect to the disclosed invention.
While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
